Fig. 10 is an enlarged view of one of the shaker bars showing the flexible connection for the gas supply.

Referring to the drawings, the numeral lO indicates the stove closed'at the front by the customary doors 11 and 12 provided with suitable grasping handles, locking means 14, and hinges. At its lower front part the stove contains a drawer 16, with handles or grips 17 for the storing of coal if such is to be used as fuel.

The gas is supplied to the stove through a suitable conduit 18 adapted to be connected to any gas supply pipe.

. A water tank 19 having an exhaust 79 is arrangedon top of the rear part of the stove and the water contained therein is heated by gas, if such is used as fuel, sup-plied through pipes 20. The water is filled into the tank through the top thereof. Shelves 21 or the like are provided in compartments 22 on top of tank 19 for the storage of dishes to be preheated or warmed and which are closed at the front by suitable sliding doors 23.

An auxiliary water tank 24: is provided on one side of the stove where the fire box is located.

- The rear of the stove shows the customary socket 25 for connection with the well known pipes leading to the chimney.

The stove is provided on top with the ordinary cover plate having a plurality of cooking or fire holes 27.

One of these holes is provided with a bottom 28 and suitable side walls to form a chamber for the reception of steaming water for cooking breakfast food such as for instance, cereal dishes, etc.

This hole is covered by a cover 29 hinged to thetop of the stove which has the usual centrally located pot-hole.

As shown in Fig. 3 the-stove is chambered and in the central chamber a gas burner 30 is located which is more fully illustrated in Figs- 8 and 9. This burner is ring shaped and is provided at its upper, as 'well as its lower face with a plurality of nipples 31 so as to heat a vessel or pot within hole 27 and cover the upper wall 32 of a baking chamber 33 belowsaid burner.

The fire bo'xfishowsthe customary re within the receiver as shown.

per wall of the fire box and are journaled within a frame 43 normally resting with each corner-upon a flat curved spring arm 45 secured to horizontal rods 44 transversely arranged within the fire box and adapted to make one half revolutionwith these rods.

The outer ends of the rods 44 are passed within suitable sleeves 46 through the tank 24am extend beyond the outer wall of the stove, where they carry other curved arms '47 similarly shaped as the arms 45,the free ends of which are connected by a rod 48 adapted to be operated by aknob 49 to execute one half revolution in one or the other direction, in order to raise'or lower the grate and its framewithin certain limits,

- as willbe clearly understood for a purpose hereinafter more fully described.

Below the grate an ash receiver 50'is secured upon an axle 51 journaled within the rear and front walls of the stove and the front end of said axle is extended beyond the outer wall of the stove and is shaped as at 52 to adapt it for engagement by a suitable tool for revolving the receiver 50 which has the shape'of a basket, the side and bottom walls of which constitute a screen 53.

In order to assist the screening operation of the ashes falling through the grate the top of the ash receiver is formed by a plurality of slats 54, transversely arranged The single slats 54 are each provided with an upwardly extending arm 55, and the upper'ends of these arms are secured to a common operating rod 56adapted to be operated by a suitable hook or tool engaging a hole 57, in the front end of said rod 56 for imparting to the rod 56 a reciprocatory movement to operate the slats 54 to regulate the draft. This rod has preferably the form of a gas pipe and is provided at its upper face with a plurality of gas nipples covered by a protector 80. A flexible tube 78 connects the rod 56 to a gas supply pipe.

The shaft 51 carries at its rear end between the rear wall of the stove and the rear wall of-the ash receiver 50, a sprocket wheel 58'onwh1ch a chain or the like 59 is guided,

,which' is also guided over a sprocket wheel 59 onthe'shaft 60 of a fan 61 for a purpose to be hereinafter more fully described.

Beneath the revolving'ash receiver 50 an ash pan 62 is provided having a central opening in alinement with a similar opening 63 in the stove bottom through which the ashes and cinders can fall, into the cellar. through an opening 64 in the floor. In case this is not desired, the holes are closed and the pan 62 can be emptied, if required by removing it through the front Wall of the stove. V V a In order to regulate the draft, numerous dampers are-arranged at various parts and in the various compartments of the stove. A damper 65 covers an opening 66 of the fan chamber 67 and is operable by a rod provided with an operating rod and knob 68. Another damper 69 covers the opening 70 leading from the top of the fan chamber 67 to the central compartment 71 and'is operable by an operating rod and knob 72, knobs 68 and 72 are shown at one side of the stove in Fig. 3. 7

To both sides of the bake-oven 73 perforated dampers 74 operable 'by'rods and knobs 75 are located, adapted to regulate the temperature prevailing within the oven, and adam-per 76 operable by a rod and knob 77 is provided 'to regulate the temperature on top of the bake oven. i

In operation either gas or'coal may be used as fuel, the former being supplied through the conduit 18 in the customary well known manner, while the 'coal stored in.

drawer 16 is piled upon the grate and ignit-ed by the ignition of the gas jets in the bar on top of the ash receiver, whichare suitably protected in order to avoid choking of the same, by dust or ashes.

The bake oven 73 is heated by gas from if a suitable burner 7 3 (Fig. 6) below its bottom and from the. side of burner 30.

If required the various dampers are suitably operated to regulate the draft and consequently the heat in the various compartments.

When coal is used as fuel the grate is gas jets on the underfrom time to time operated in'the usual manner by a suitable tool so that theashes will be sifted while simultaneously'the' fan 61 is operated to suck the developingdust out of the fire box into the socket to the chimney.

It will be clear that changes can be made in the form and shape and general arrangemen of the parts 'constitutingthe stove in accordance with the present invention with- 25 leading out departing from the scope or spirit of my invention, but what I claim, and desire to secure by Letters Patent isv i V 1.
